Research Interests
*Development of hybrid nanoparticles containing potential surfactants and silica nanoparticles for gene delivery to cancer cells.
*Study on the role of chemical structures of non-viral vectors in the gene delivery to cancer cells.
*Development of photo-triggered cancer drug delivery systems with real-time monitoring through the NSET mechanism.
*Development of fluorescent surfactant-based nucleic acids detection and gene delivery systems, and bioimaging.
*Applications of fluorescence properties of novel host-guest complexes toward the development of molecular logic gates for the detection of toxic anions in the ppb range.
*Study on protein-surfactant, nanoparticle-conjugated protein-surfactant, and DNA-surfactant interactions.
*Design and synthesis of new fluorescent probes sensitive to the polarity and rigidity of microenvironment and their applications toward biological systems (For synthesis collaborating with Prof. Tanmay Chatterjee, Professor in the Deptt. of Chemistry, BITS Pilani, Hyderabad Campus)
